It's funny that the topic is going to GPS..?? I haven't gotten to my tinySA yet because I have been finishing up my last project.
I built a GPS corrected VFO basically from a QEX article.
I am using a cheap $3.50USD NEO-6 and Arduino nano, to control an Si5351 using the 1PPS, count averaged over 40seconds.
Works great, I was able to finally calibrate my old HP counter.? Can generate any freq the 5351 can put out, jitter free.
The main purpose of this project was to get an accurate cheap shack UTC clock though.
